Answer:

6

Explanation:

The coordination number of a particular crystal structure arrangement is defined as the number of nearest neighbor atoms or ions surrounding an atom or ion.

We must note that in salts of the type MX, the coordination number of each ion must be equal. The structure of LiCl is built by placing each unit cell next to another such that ions residing in the corner, edge or face sites are shared between adjacent unit cells. The LiCl is in FCC arrangement.

Hence in LiCl, each Li+ ion is surrounded by 6 chloride ions.

Analyze: The metallic character of an element is determined by how readily it loses electrons. Elements that lose electrons most
GenaCL600 [577]

Answer:

Group 1 or akali metals have the greatest metallic property.

Group 17 has the lowest metallic character.

C. As you move from right to lefton the periodic table, metallic character increases which is the ability to lose electrons. Ionization energy decrease as we move from right to left on the periodic table.

Explanation:

Akali metals in group 1 have the greatest metallic property and they are the most reactive metals. Francium metal on the group has the most metallic characteristics. It is rare and very radioactive. Group 17 has the lowest metallic character. This is because while moving across the period, the number of electrons in the outermost shell increases. This make it difficult for atoms to leave see electrons and become electropositive . Group 17 has the highest tendency of accepting electrons.

Ionization energy is the energy use to remove electron from an atom in gaseous stage. Ionization energy decrease as we move from right to left on the periodic table and metallic character increases as we move from right to left on the periodic table.

Which electron transition represents a gain of energy?
xz_007 [3.2K]

The correct answer is (A) from 2nd to 3rd shell.


The explanation :


when a gain of energy is the shift of the electrons from a shell of low energy to the shell of high energy


and we have here 2nd shell is the shell of low energy, and 3rd shell is the shell of high energy.


∴ (A) from 2nd to 3rd shell is the correct answer.

___ Particles of which of the following have the greatest thermal energy
abruzzese [7]
Salutations!

<span>___ Particles of which of the following have the greatest thermal energy

Gas is the particle that has the greatest thermal energy. Gas has the greatest thermal energy because the movement between particles is clump. This thermal energy is then converted into kinetic energy.

Thus, your answer is option C.

Hope I helped (:

Have a great day!</span>

What will happen if a peeled banana is put on a hotplate? Will it undergo a physical or a chemical change?
FinnZ [79.3K]
I would say physical, because a physical change is affecting the form of a chemical substance, but not it's chemical makeup.
